I have had 2 spinal fusions, the last one being October 22 2013. I recently got a CT scan and saw my neuro today and she said that the bone isn't healing well at all, it is less than half as thick as it should be at this point. She took bone from my rib compared to using cadaver bone so that the fusion would heal better, thank goodness that she did. She said it would have failed if we would have used cadaver. Has anyone else had this happen and what was the end result? I see my neuro again in 6 months since I have in both my surgeries been a high risk patient. I don't have any of the risk factors that would explain why this is happening. Would love to hear from anyone who has had this or has heard of this. Thanks in advance!
